Mining power cable and production technology thereof

Abstract

The invention relates to a mining power cable and a production technology thereof. The mining power cable comprises a conductive wire core, a neutral wire core, a tensile nylon rope, a tinned copper wire and steel wire braid layer, a flame retardant fire-resistant layer and a black chloroprene rubber outer sheath, wherein the conductive wire core is formed by coating and twisting a copper conductor with a mineral synthetic mica tape; a polytetrafluoroethylene insulating layer coats the surface of the conductive wire core; the neutral wire core comprises a twisted copper conductor and a glass fiber core; the twisted copper conductor extrudes and wraps the glass fiber core; the polytetrafluoroethylene insulating layer coats the surface of the neutral wire core; the outer sides of the conductive wire core and the neutral wire core are sequentially coated with the tensile nylon rope and the tinned copper wire and steel wire braid layer and then extruded and wrapped into a cable core; and the surface of the cable core is extruded and wrapped with the flame retardant fire-resistant layer and the black chloroprene rubber outer sheath from the inside to the outside. The mining power cable is simple in structural design, low in smoke, free of halogen, fire-resistant, convenient to install and lay, good in flexibility and good in safety performance; and internal and external electromagnetic interference is effectively suppressed.

Description

technical field [0001] The invention relates to a power cord and a production process thereof, in particular to a power cord used for coal mining operations and a production process thereof. Background technique [0002] Mine power cord refers to the wire and cable products used to supply power to ground equipment and underground equipment used in the coal mining industry. Since the power supply in the coal mining area is a weak link in the power supply system and the working environment is poor, the power cord is a key component to ensure the stable and safe operation of the power supply system, and the requirements for mining power cords are particularly high. Existing mining power cords have problems of wear resistance, poor acid and alkali corrosion resistance, and unsatisfactory flame retardant and fire resistance effects during use. Moreover, due to the insufficient flexibility and mechanical strength of the power cord, the power cord is often bent and broken during us...

AI Technical Summary

Problems solved by technology

Existing mining power cords have wear resistance, poor acid and alkali corrosion resistance, and unsatisfactory flame-retardant and fire-resistant effects during use, and because the softness and mechanical strength of the power cord are not good enough, the power cord often bends and breaks during use Therefore, there is an urgent need for a mining power cord with good electrical performance and long service life to solve the above technical problems
